Abstract

This letter reports a scanning electron microscopy investigation of surface acoustic wavediffraction on the zigzag domain wall in a Gd2(MoO4)3 crystal. The zigzag domain wall with ∼80 μm period was formed in a Gd2(MoO4)3 crystal by applying the external mechanical stress. It is shown that the surface acoustic wavediffracts on the zigzag domain wall in a ferroelastic Gd2(MoO4)3 crystal.
